TypePad, our host, has been undergoing Distributed Denial of Service attacks that have interrupted this blog and many others. A particularly ghastly side-effect of these attacks is that all domain names using TypePad (such as humantransit.org) are leading to an "Unknown Domain Name" error, giving the false impression that we're out of business. TypePad writes on their blog:
While most blogs are available and the application is up, some mapped domains are showing a message that the domain is "unknown", but there is no problem with the domain itself. We're working to correct the error on our end.
For the record, we still exist, and our domain name hosting is current. If anyone tells you we're out of business, please correct them!
